1 ADC0844/ADC Bit µp Compatible A/D Converters with Multiplexer Options General Description The ADC0844 and ADC0848 are CMOS 8-bit successive approximation A/D converters with versatile analog input multiplexers. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation. The differential mode provides low frequency input common mode rejection and allows offsetting the analog range of the converter. In addition, the A/D s reference can be adjusted enabling the conversion of reduced analog ranges with 8-bit resolution. The A/Ds are designed to operate from the control bus of a wide variety of microprocessors. TRI-STATE output latches that directly drive the data bus permit the A/Ds to be configured as memory locations or I/O devices to the microprocessor with no interface logic necessary.

Note 9: For V IN ( ) V IN (+) the digital output code will be Two on-chip diodes are tied to each analog input, which will forward-conduct for analog input voltages one diode drop below ground or one diode drop greater than V CC supply. Be careful during testing at low V CC levels (4.5V), as high level analog inputs (5V) can cause this input diode to conduct, especially at elevated temperatures, and cause errors for analog inputs near full-scale. The spec allows 50 mv forward bias of either diode. This means that as long as the analog V IN does not exceed the supply voltage by more than 50 mv, the output code will be correct. To achieve an absolute 0 V DC to5v DC input voltage range will therefore require a minimum supply voltage of V DC over temperature variations, initial tolerance and loading.

10 ADC0844/ADC0848 Functional Description The ADC0844 and ADC0848 contain a 4-channel and 8-channel analog input multiplexer (MUX) respectively. Each MUX can be configured into one of three modes of operation differential, pseudo-differential, and single ended. These modes are discussed in the Applications Information Section. The specific mode is selected by loading the MUX address latch with the proper address (see Table 1 and Table 2). Inputs to the MUX address latch (MA0-MA4) are common with data bus lines (DB0-DB4) and are enabled when the RD line is high. A conversion is initiated via the CS and WR lines. If the data from a previous conversion is not read, the INTR line will be low. The falling edge of WR will reset the INTR line high and ready the A/D for a conversion cycle. The rising edge of WR, with RD high, strobes the data on the MA0/DB0-MA4/DB4 inputs into the MUX address latch to select a new input configuration and start a conversion. If the RD line is held low during the entire low period of WR the previous MUX configuration is retained, and the data of the previous conversion is the output on lines DB0-DB7. After the conversion cycle (t C 40 µs), which is set by the internal clock frequency, the digital data is transferred to the output latch and the INTR is asserted low. Taking CS and RD low resets INTR output high and outputs the conversion result on the data lines (DB0-DB7). Applications Information 1.0 MULTIPLEXER CONFIGURATION The design of these converters utilizes a sampled-data comparator structure which allows a differential analog input to be converted by a successive approximation routine. The actual voltage converted is always the difference between an assigned + input terminal and a input terminal. The polarity of each input terminal of the pair being converted indicates which line the converter expects to be the most positive. If the assigned + input is less than the input the converter responds with an all zeros output code. A unique input multiplexing scheme has been utilized to provide multiple analog channels. The input channels can be software configured into three modes: differential, single ended, or pseudo-differential. Figure 1 shows the three modes using the 4-channel MUX ADC0844. The eight inputs of the ADC0848 can also be configured in any of the three modes. In the differential mode, the ADC0844 channel inputs are grouped in pairs, CH1 with CH2 and CH3 with CH4. The polarity assignment of each channel in the pair is interchangeable. The single-ended mode has CH1 CH4 assigned as the positive input with the negative input being the analog ground (AGND) of the device. Finally, in the pseudodifferential mode CH1 CH3 are positive inputs referenced to CH4 which is now a pseudo-ground. This pseudo-ground input can be set to any potential within the input commonmode range of the converter. The analog signal conditioning required in transducer-based data acquisition systems is significantly simplified with this type of input flexibility. One converter package can now handle ground referenced inputs and true differential inputs as well as signals with some arbitrary reference voltage. The analog input voltages for each channel can range from 50 mv below ground to 50 mv above V CC (typically 5V) without degrading conversion accuracy. TABLE 1.

11 Applications Information (Continued) 4 Single-Ended ADC0844/ADC Differential Pseudo-Differential Combined FIGURE 1. Analog Input Multiplexer Options 2.0 REFERENCE CONSIDERATIONS The voltage applied to the reference input of these converters defines the voltage span of the analog input (the difference between V IN(MAX) and V IN(MIN) ) over which the 256 possible output codes apply. The devices can be used in either ratiometric applications or in systems requiring absolute accuracy. The reference pin must be connected to a voltage source capable of driving the minimum reference input resistance of 1.1 kω. This pin is the top of a resistor divider string used for the successive approximation conversion. In a ratiometric system (Figure 2a), the analog input voltage is proportional to the voltage used for the A/D reference. This voltage is typically the system power supply, so the V REF pin can be tied to V CC. This technique relaxes the stability requirements of the system reference as the analog input and A/D reference move together maintaining the same output code for a given input condition. For absolute accuracy (Figure 2b), where the analog input varies between very specific voltage limits, the reference pin can be biased with a time and temperature stable voltage source. The LM385 and LM336 reference diodes are good low current devices to use with these converters. 11
12 ADC0844/ADC0848 Applications Information (Continued) The maximum value of the reference is limited to the V CC supply voltage. The minimum value, however, can be quite small (see Typical Performance Characteristics) to allow direct conversions of transducer outputs providing less than a 5V output span. Particular care must be taken with regard to noise pickup, circuit layout and system error voltage sources when operating with a reduced span due to the increased sensitivity of the converter (1 LSB equals V REF / 256). 3.0 THE ANALOG INPUTS 3.1 Analog Differential Voltage Inputs and Common-Mode Rejection The differential input of these converters actually reduces the effects of common-mode input noise, a signal common to both selected + and inputs for a conversion (60 Hz is most typical). The time interval between sampling the + input and then the inputs is 1 2 of a clock period. The change in the common-mode voltage during this short time interval can cause conversion errors. For a sinusoidal common-mode signal this error is: where f CM is the frequency of the common-mode signal, V peak is its peak voltage value and t C is the conversion time. For a 60 Hz common-mode signal to generate a 1 4 LSB error ( 5 mv) with the converter running at 40 µs, its peak value would have to be 5.43V. This large a common-mode signal is much greater than that generally found in a well designed data acquisition system. TABLE 2.

These currents decay rapidly and do not cause errors as the internal comparator is strobed at the end of a clock period. Bypass capacitors at the inputs will average these currents and cause an effective DC current to flow through the output resistance of the analog signal source. Bypass capacitors should not be used if the source resistance is greater than 1kΩ. 3.3 Input Source Resistance The limitation of the input source resistance due to the DC leakage currents of the input multiplexer is important. A worst-case leakage current of ± 1 µa over temperature will create a1mvinput error with a1kω source resistance. An op amp RC active low pass filter can provide both impedance buffering and noise filtering should a high impedance signal source be required. 12
13 Applications Information (Continued) 4.0 OPTIONAL ADJUSTMENTS 4.1 Zero Error The zero of the A/D does not require adjustment. If the minimum analog input voltage value, V IN(MIN), is not ground, a zero offset can be done. The converter can be made to output digital code for this minimum input voltage by biasing any V IN ( ) input at this V IN(MIN) value. This is useful for either differential or pseudo-differential modes of input channel configuration. The zero error of the A/D converter relates to the location of the first riser of the transfer function and can be measured by grounding the V input and applying a small magnitude positive voltage to the V + input. Zero error is the difference between actual DC input voltage which is necessary to just cause an output digital code transition from to and the ideal 1 2 LSB value ( 1 2 LSB=9.8 mv for V REF =5.000 V DC ). 4.2 Full-Scale The full-scale adjustment can be made by applying a differential input voltage which is LSB down from the desired analog full-scale voltage range and then adjusting the magnitude of the V REF input for a digital output code changing from to Adjusting for an Arbitrary Analog Input Voltage Range If the analog zero voltage of the A/D is shifted away from ground (for example, to accommodate an analog input signal which does not go to ground), this new zero reference should be properly adjusted first. A V IN (+) voltage which equals this desired zero reference plus 1 2 LSB (where the LSB is calculated for the desired analog span, 1 LSB = analog span/256) is applied to selected + input and the zero reference voltage at the corresponding input should then be adjusted to just obtain the 00 HEX to 01 HEX code transition.

14 ADC0844/ADC0848 Applications Information (Continued) The full-scale adjustment should be made [with the proper V IN ( ) voltage applied] by forcing a voltage to the V IN (+) input which is given by: where V MAX =the high end of the analog input range and V MIN =the low end (the offset zero) of the analog range. (Both are ground referenced.) The V REF (or V CC ) voltage is then adjusted to provide a code change from FE HEX to FF HEX. This completes the adjustment procedure. For an example see the Zero-Shift and Span Adjust circuit below. Zero-Shift and Span Adjust (2V V IN 5V) Differential Voltage Input 9-Bit A/D
